Hopefully this is a good place to ask this, but do any of you long-time comiccers have any tips on getting a comic down to under 200kb? I submitted a pretty long comic (around 3k pixels tall) and I was able to get it down to a 200kb JPEG while still being legible, but it ended up pretty crunchy. I'd like to try to avoid the artifacting in the future if I can. Would adopting a more limited-color style help? Or even just going grayscale/using halftones? What causes this much artifacting on JPEGs, especially around areas of text, and how can it be avoided? Kengplant has a pretty good guide here of the basics of comic compression: www.neopets.com/ntimes/index.phtml?section=590081&issue=998But Keng based it off conversations with existing artists, and experimentation. I'll try to summarize my experience, at least. Limited color palette does help. Grayscale is one way to go limited palette, but not the only way. Also try scaling down the comic after the sketch phrase, before lineart, instead of at the end. Drawing the comic at scale (470px or less) is a big help in compression, though it does make it less portable to posting elsewhere. Try gif instead of jpg; it can make a difference in size, and sometimes the quality doesn't really suffer.

Of course, I was doing traditional, which has it own whole set of tips, like: When you scan, do so as a high-resolution tiff, then after you've played around with the saturation and color in a photo-editor, scale down and then save as a gif or jpg. Traditional is harder to compress, but if you've scanning as a jpg, and then doing gif, well, you end up with weird artifacts, it's much cleaner to go through tiff first when scanning.
